Ancona ducks (Anas platyrhynchos domesticus) are critically endangered rare ducks, considered to be a descendant of the Indian Runner Duck and the Belgian Huttegem Duck breeds. Most are black and white, but they come in a variety of colours including: Black and White, Blue and White, Chocolate and White, Silver and White, Lavender and White, and Tri-coloured. Ancona ducks make good pets because they do not migrate, do not even fly, and like staying close to home.
